Only the Gospel of John, 5:1-9, tells the story of this miracle.
At the sheep market in Jerusalem was a pool with healing properties. At certain times an angel would come down to "trouble" the water, curing the disease of any ailing person who would step in.
When a man with an infirmity for 38 years told Jesus he was unable to get to the pool, "Jesus saith unto him, Rise, take up thy bed, and walk. And immediately the man was made whole, and took up his bed, and walked".
